Thanks Jarno, true enough.

So to return the third node from the following:

  <node> </node>
  <node>&#160;</node>
  <node>test</node>

I'm going to use: 

string(translate(., ' &#160;', ''))

Any improvements, suggestions on that?  I can't think of any other
whitespace (well, apparent whitespace) characters...

cheers
